i think there are 2 solutions..
this is how i've done --->
|[x]-2x|=3
=> [x] - 2x = 3 or [x] - 2x = -3
=> [x] = 2x + 3 or [x] = 2x - 3
since. LHS is an interger in the above equations, therefore RHS has to be an integer, & for that, x has to be an integer or x should be 1/2
but x = 1/2 does not give the solution
=> x has to be an interger
so, [x] = x
=> x = -3 or x = 3
therefore, there are 2 solutions
plz correct me if i'm wrong anywhere ....
